During turning, the cutting force of the cutter on the workpiece can be decomposed into axial force, radial force and tangential force. Wherein the radial cutting force directly pushes the elongate shaft to cause it to flex elastically. Because the distance between the supporting points of the slender shaft is large, the radial force easily causes larger deflection at the middle part of the workpiece. The self gravity of the slender shaft can cause the slender shaft to generate sagging deflection in the axial direction, and particularly when no auxiliary support is provided, the sagging can be aggravated along with the position change of the cutter in the processing process, so that cylindricity errors of the processed workpiece can be caused.
